IMPROVEMENT IN AUTOMATIC FANS.

Specification forming part of Letters Patent No. 186,473, dated January23, 1877 5 application filed July 22, 1876.

To all whom it may concern:

Be it known that JAMEs'M. GRAY, de-

ceased, late of Valdosta, in the county of Lowndes and State of Georgia,invented a new and Improved Fly-Fan, of which the following is aspecification:

In the accompanying drawing, Figure 1 represents a front view of thisimproved flyfan, and Fig. 2 a modified form of the lever and pivot. a

. Similar letters of reference indicate corresponding parts.

The invention relates to an automatic fan for keeping oft flies fromdinner-tables, sickbeds, sleeping infants, and also for fanning at nightto keep off mosquitoes and produce a l the fan-vibrator G.

The latter is rigidly attached to shaft a, on which is fixed across-bar, b. D is a yoke,

which has two projecting arms, d, that work through guides in the endsof cross-bar, so as to give the necessary play to the yoke and vibratethe cross-bar.

The fan-socket E is applied by a pivot and clamp-screw to the lower endof the lever O, to be adjusted thereon at any suitable angle.

The fan is fastened by a clamp-screw to the socket, and a fan of anysuitable size or shape, or a number of them, placed in connection withthe lever, as desired.

The clock-work and transmitting mechanism are incased in a suitable box,that may be attached to the wall, ceiling, bed, or other point, to movethe fan horizontally or vertically, as desired, the operating mechanismbeing simple, and producing a regular and reliable motion of the fan.

' The speed of the fan may be regulated. in the customary manner, by asuitable springbrake and regulating-scremthat acts on a ,friction-wbeelplaced .on the shaft of one of the transmitting-wheels of theclock-train.

By giving the yoke a sliding motion it is not necessary to make thelength fully equal to double the diameter of the eccentric or double thelongest distance from its center of motion to its periphery, it beingthus rendered possible to arrange the mechanism more compactly.

Having thus'described the invention, it is claimed as new and desired tosecure by Letters Patent- The combination, with clock mechanism, of thedriveshaft, having pinion and eccentric, the sliding yoke D, the shafthaving crossbar I), and the vibrator O, in order to operate the socketE, in the manner specified.
